One of the most interesting data sets for aspiring mapmakers is the Census Bureau’s American Community Survey. Among other things, that survey includes a detailed look at the languages spoken in American homes. All the maps below are based on the responses to this survey. For instance, Mandarin, Cantonese, and Chinese are separated as different responses in the data, so were treated as different languages when constructing these maps. If those languages had been grouped together, the marking of many states would change.

Besides the most common languages, the maps are broken down into the most common Native American languages, most common Scandinavian languages, and more.
